U.S. Olympic luger Kate Hansen fooled millions of people Thursday after tweeting a video of a wolf roaming her dorm's hallway in Sochi. 24 hours after it was posted, the YouTube video currently has nearly 2 million hits.

Turns out, prankster Jimmy Kimmel was behind the "Epic #SochiFail."

Kimmel revealed his involvement on last night's "Jimmy Kimmel Live!" telling viewers, "Here's the thing: That was not a Russian wolf. That was an American wolf. And I know this because the wolf is backstage right now. We shot the video and Kate Hansen posted it for us from her account and a media frenzy was born."

Kimmel then played the full, un-edited version of the video, in which he later appears in a ski suit, asking, "Garfield? Garfield? Have you seen my wolf?"YouTube/ABC "Jimmy Kimmel Live!"

After posting the video, Hansen told viewers "I just kind of laid low but then I heard people talking around the building and security started freaking out because it technically was a breach within athlete safety."

"It kind of went a little crazy over here," she added.

After the late night host asked Hansen if she got in any trouble for the gag, she revealed, "Honestly, there was a little more backlash than I thought there would be ... but it was all worth it in the end."
